Charles Ellicott Commentary 2 Samuel 22:23

"For all his ordinances were before me; And as for his statutes, I did not depart from them." — 2 Samuel 22:23 (ASV)

His statutes, I did not depart from them. —The psalm, by a very slight change in the original, has “I did not put away his statutes from me.” The former is the more common form; the latter suits the parallelism here better.
